The present invention relates to a coin delivering mechanism for coin-controlled vending apparatus of the type in which a coin or token is deposited in the apparatus by means of a coin inserting mechanism and thereby releases a goods delivering mechanism which normally is locked.

The invention is mainly distinguished in that a driving organ is arranged at the inner end of the coin inserting mechanism at which the coin is discharged, so that the coin, during the dischargement, acts upon said organ which thereby starts or operates a coin delivering mechanism, in order to deliver a number of coins, the value of which corresponds to the difference between the cost of the delivered goods and the value of the inserted coin or coins.

lhe invention may be used in connection with coin-controlled vending apparatus provided with a coin inserting mechanism of any type, but in the present case it will be described in connection with a coin inserting mechanism of the type described in my co-pending application No. 739,969, filed Aug. 15, 1934 (Patent No. 2,022,944) with reference to the accompanying drawing in which,

Figure 1 is a vertical section through the mechanism along the line II of Figure 3,

Figure 2 is a front view of the mechanism,

Figure 3 is a plan view of the same,

Figure 4 is a section on the line IV-IV in 30 ure '1, and

Figure 5 is a section on the line V-V in Figure 1.

In the drawing and 2 denote two frames between which is secured a sleeve 5 in which is rotatably mounted a sleeve shaped member 6 which encompasses a stationary screw 1 and controls the goods delivering mechanism.

On a shaft 20, which is secured in the frames 2, is swingably mounted a locking piece 2| which 40 normally extends through an opening 5' in the sleeve 5, projects into an axial slot 22 in the membar 6 and protrudes into the path of the side edge 23 of the slot 22 and prevents rotation of the member 6.

28, 28', 28" and 28 denote tubes or channels by means of which coins or tokens may be inserted through openings 38 in the sleeve 5 into the slot 22 in the member 6, when this is in its starting position, and into a thread of the screw 1 at predetermined points thereof so that the coin rests against the bottom of the thread and against the side edge 23.

When a coin is inserted through channel 28 into the member 6 and this is rotated, the coin raises the locking piece 2| so that the edge 23 Figmay pass below it as shown in Figure 1. Immediately after the coin has raised the locking piece 2| so that the edge 23 may pass, the coin impinges upon an inclined plane 4|, arranged in the thread, along which the coin by means of the following edge 23, is forced out through a slit 42 in the sleeve 5.

If a coin is inserted through channel 28' into the member 6 and this is rotated the coin, after having raised the locking piece 2| the first time as above mentioned, is forced by means of the side edge 23 along the thread of the screw 7, While the member 6 accomplishes its first revolution, so that the coin again occupies a position corresponding to the starting position, but displaced in the axial direction of the screw a distance corresponding to the pitch of the thread. During the rotation the coin is held into the thread by means of the sleeve 5. During the continued rotation of the member 6 the coin again raises the locking piece 2|, and impinges thereafter upon an inclined'plane 4| along which it is forced out through a slit 42'. oqmplished the second revolution it is again locked by the locking piece 2|. If a coin is inserted into the member 6 through channel 28 or 23 the locking piece will be raised in the manner described above three or four times respectively, before it, by means of inclined planes 4!" or 4| respectively is forced out through slits 42 or 42", respectively.

In the case of the price of the goods delivered not corresponding to the value of the inserted coin or coins, a coin delivering mechanism is arranged which delivers one or more coins corresponding to the difference.

In front of each of the slits 42 in the sleeve 5, through which the coin is forced out from the member 6, is placed a lever 59 the upper end of which is swingably mounted, preferably on the shaft 20. The lower end of said lever has a tap 69 which projects into a slit 6| in a lever 63 swingably mounted on a shaft 62. Each of the levers 63 is at its upper end connected with a horizontal displaceable bar 64 provided at one end with a head shaped cross piece 65. The bars, which are guided in a vertical wall 66 and in a wall 61 by means of guiding pins 68, are arranged one above the other so that the cross pieces 65, which are all of the same length, normally are placed in position one above the other.

In each of the cross pieces 65 is arranged a number of bores 65' for removable pins 69 which, during the displacement of the bars, are moved forwards through holes 61' in the wall 61. The

When the member 6 has acbores in the cross pieces are so arranged that they form vertical rows, in the embodiment shown, five rows with four bores in the height.

Above the bars 64 are placed a number of coin containers 10, 10a, 10b, 10c and 10d, and at the underside thereof is for each of the containers displaceably mounted an emitter H which act upon the lowermost coin in the respective container and emits the same into a funnel 12 leading to a bowl or the like at the outer side of the apparatus. Each of the emitters II is secured to a displaceable bar 13 which bars, placed in a horizontal row, are guided on shafts l4 and acted upon by springs 15 which always return the bars to the starting position. Each of the bars 13 is provided with a downwardly projecting arm 16 and as the bars are placed in a horizontal row, the arms 76 will project downwardly in line with each of the rows of bores in the cross pieces 65.

A coin which is forced out through the slit 42 in the sleeve 5 as shown in Figure 1, presses the lever 59 outwardly so that the lever 63 is swung outwardly also and displaces the corresponchng bar 84 to the right in Figure 1. By this movement the pins 69 on the cross piecethe number and position of said pins are dependent on which of the emitters are to be operatedact upon the arm 16 in front thereof and emit a coin from the corresponding container, so that said coin falls down in the funnel 12. After this has occurred the members are returned to the starting position by means of the spring 15 or other springs for that purpose.

Assuming that the coin dropped into the channel 28 is a fifty cent piece, that the selling price of the goods delivered by rotating the member 6 one revolution is thirty-five cents, and that the coin containers are of such a size that the container 0 and a receive nickels 70b quarters, 10c and 10d dimes, the mechanism will act in the following manner: When the coin, after one revolution of the member 6 is forced out through the slit 42 the lever 59 outside the same is swung outwardly and acts upon its lever 63, which displaces the lowermost bar 64 to the right in Fig. l. During this movement the pins 69 in the cross piece 65 of said bar act upon the arms 16 which are connected with the emitters of the containers I0 and so that said emitters are displaced and thereby emit a dime from container 100 and a nickel from container 10.

By placing the pins 69 in different bores it is possible to emit a coin from one, more or all of the containers so that the correct change may be delivered.

As will be understood the detailed construction may be varied in many ways .without departing from the scope of the invention, and the mechanism may be adapted to delivery apparatus of different type and operation.

I claim:

1. In a coin-controlled vending apparatus having a casing with a plurality of outlets for the operating coin, a spring pressed member for each of said outlets in the path of an operating coin discharged therefrom, change coin containers for coins of various values, movable coin emitters at the bottom of said containers and emitting a coin at each actuation thereof, and means operatively connecting each of said coin emitters with certain of said spring pressed members, the connection between the spring pressed members and the coin emitters comprising a lever to which said spring pressed member is attached, spring pressed 1 bars attached to said levers and having cross pieces, each said cross piece having bores therein and pins adapted to fit said bores, and an arm on each coin emitter in the path of said pins when said cross pieces are moved whereby coins from selected containers may be emitted at each actuation of the spring member.

2. Coin-controlled apparatus comprising a stationary screw, a rotatable longitudinal sleeveshaped member surrounding said screw and having a longitudinal slot therein, means for guiding a coin into said slot and into engagement with the threads of said screw and one side of said slot whereby rotation of the sleeve-shaped member moves the coin longitudinally of the slot and a plurality of individual means for forcing the coin out of engagement with the threads of the screw arranged at unequal distances along the axis of the screw, a spring pressed member opposite each of said forcing means, a plurality of containers for change coins of various sizes, a coin emitter for each of said containers and selective means for connecting said coin emitters to said spring pressed members.
